Auplicaticn filed December 1, 1904. Serial No. 235,103.

To an whom, it may concern.-

Be it known that I, CALVIN N. PAYNE, a citizen of the United States,residing at Titusville, in the county of Crawford and State ofPennsylvania, have invented new and useful Improvements in SpeedDevices, of which the following is a specification.

This invention. relates to speed devices; and it consists in certainimprovements in the construction thereof, as will be hereinafter fullydescribed, and pointed out in the claims.

The invention is particularly adapted to speed-changin devices used withautomobiles and as shown is designed particularly for this use.

Among the important features of the invention are devices through whichvarious speeds may-be brought into action by. the continuous movement ofthe controlling mechanism in one direction. In other words, it is notnecessary to bring the controlling mechanism to a neutral point toarrange the mechanism for the various speeds. The mechanism for eachspeed may be coupled u or released by the movement of the contro lingmechanism either to the next higher speed or next lower speed, and themovement of the controlling mechanism in either direction releases themechanism just previously in action.

he other features of the invention will a pear from the followingdescription of $1 1 6 claims.

The invention is panyin drawings, as follows: a side c evation of thedevice; Fig. 2, a View from the opposite side of the device; Fi 3, asection on the line 3 3 in Figs. 1 and. 2; Fig. 4, a section on the line4 4 in Fig. 3, a part being broken away and in section to better show 5,a section on the line 5 5 in Fig. 3 Fi 6, a detail of the controllingmechanism; ig. 7, a section of said mechanism on the line 7 7 in Fig. 8;Fig. 8, a section on the line 8 8 in Fig. 6.

Alnarks thedrive-shaft, and B thedriven shaft. The driven shafthas thesleeved end B, whichpver'laps the driving-shaft A. The shaft'A ismountedin the bearing n supported'on th'epost N, baseNof the case. shaft A iscarried in the sleeve end B", and

the sleeve B is carried by the bearing n ythe bearing n being supportedby the post N illustrated in the accent Figure 1 shows extending fromthe The other end ofithe extending from the base N. The shaft B is alsocarried by the hearing it, supported by the post N this post alsoextending from the base N.

The drive-sleeve O is j ournaled on the 6c drive-shaft A. It is providedwith the ballopenings 0, in which are arranged the clutchballs 0. Theshaft A is provided with clutch-slots a, into which the balls 0 ma beforced for locking the sleeve C with the s iaft 6 The mechanism foraccomplishin this comprises the strap I, caln and lip 1 the lip i beingso formed as to prevent the move ment of the balls out of the openin s6, but to permit a sufficient movement of t 1e balls to clear the shaftA, so as to release the clutch. The strap 1 is provided with acircumferential groove 1', in which the pins i are arranged. These pinsare carried by the rock-arms I. The rock-arms I are carried by the shaftI 7 5 (See Fig. 5.) The shaft I is carried by the osts N extending fromthe base N. Arockever I extends from the end of the shaft, and the pin 1of this rock-lever extends into a cam-slotP,arranged in thecam-platcP.The cam-plate P ismounted on the face of'the gear 0. This gear iscarried by the bearing 12, and the bearing n is supported by the post N,ex-' tending from the base N. A rack O is slidingly mounted in theuprights N extending from said base. The shank O of this rack isconnected to the cross-head J. The crosshcad J issecured 'to theoperating-lever K. When the lever K is at the neutral oint, the pin I isat the point p in the camot. (See 0 Fig. 1.) As this lever is movedforward, the rack olperatin upon the ear 0 moves the cam-p ate an. thecam-s ot, so as to bring the pin 1 into the part 1) of the cam-slot.This compels a movement of the rock-lever I 5 and a consequent movementof the strap I, so as to pressthe balls through the action on the cam iand set the clutch.

A series of gears D, D, D, and D are fixed on the drive-sleeve O.Areverse-gear D is [00 also fixed on this sleeve and meshes theintermediate gear D A transmission-shaft F is mounted in the bearing nn, sup orted by the posts N 3 N extending from t 1% plate N. This shaftis hollow and-has mounted upon it the gears E, E, E ,and Emeshing,respectively; the gears D, D, Dhand D It has a'lsothereverse-gear E, the shing the intermediate gear D, it being driven bythe "gear DI: The 1 I0 gears E, E, E, E, and E are provided with theclutch-slots e, e, c c and 6, respectively, The ball-openings f, f,f,f", awlf" are cut through the hollow shaft 11 in the paths of the slots6, c. (2*, e, and a", respectively, and these openings are provided withthe clutch-balls f f f, and f", respectively. When these clutch-ballsare forced out into the clutchslots they lock the gear into which theyare forced with the transmissiornshaft. When, however, the balls. areallowed to re,- cede in the ball-openings out of the clutch slots in thegears, the gears are free to turn on the shaft, the gears being loosethereon. In the operation of the device, therefore, only the gear givinga desired speed is locked with the transmission-shaft. All the othergears, while they remain in mesh, turn freely on said shaft.

A controlling device is arranged in the hollow shaft F and is adapted toforce the balls into the clutch-slots. it comprises the rod J. This issecured to the cross-head J by means of the nut The rod J has thelongitudinal groove j. This groove is of sufiicient depth to permit theballs in register with the groove to move through the ball-openings asufficient distance to bring them out of the path of the gears, or, inother words, to release the cars from the shaft. The rod J is lockedagainst axial movement by the key j which is arranged in the inner partof the shaft and projects into the grooves f in the rod, so that thegroove is at all times inregister circunn ferentially with the balls.Aball-actuating device 3' is journaled on the pin j, extending from theend of the rod J. This ball-actuat ing device has the groove i whichcorres )onds to the groove when. line therewith. tuating device j isbeveled so that as the rod J, and with it the ball-actuating device, ismoved through the shaft this surface j" engages the balls and forcesthem up through the openings in the clutch-slots to set the clutch.Ordinarily the device would be started at the neutral point and wouldfirst pick up the low-speed gear E and then the gears of the higherspeed-gears E, E and E successively. The ballactuating device. is not ofsufficient length to hold more than one set of balls in engagement atone time, and as it passes from under the balls they drop into thegroove j, thus releasing the clutch from.

the gear just previouslylocked with the transmission-shaft. It may alsobe moved from the neutral point to the reverse gear E. Here the oppositeend of the ball-actuating device engages the ball but it is so shaped asto effect this result. It may happen in the o eration of an automobileand of other ma ciiinery to which this may be a plied that the machineis stopped with the c utch set in the high gear. It is desirable to beable to brought into. The front end of the ball-ac-,

bring the controlling mechanism to the neutral point and to release theclutch from the high gear before starting the machine. therefore mountthe ball-actuating device rotatively and provide it with. the grooves jand cam-surfaces j". The cam-surfaces contacting the balls which areheld to the inner position by the inner surfaces of the gears turn theball-actuating device on the pin j, so as to bring the groove j intoregister with the groove j, and thus permit the passage of theball-actuating device past the balls.

Any convenient mechanism may be used for normally holding the actuatingdevice in osition to force the balls into clutch relation. l have,however, arranged the following mechanism: The front end. of theball-actuating device is provided with the cam j", which engages. a camj on a camblock The cam-block is mounted on the pin j, but is lockedagainst rotative movement by the pin which extends into the cam-blockand slidingly into the o enings j in the end of the extension J Springs1 are'mounted in the openings j so as to press against the pins j. Asthe ball-actuating device j is turned through the action of thecam-surfaces. j on. F acting against the cam-block forces the cam-blockagainst the spring. As soon as the ball-actuating device passes by theballs the springs acting on the block 7' through the action ofthe cams jand 7 force the hallactuating device back to its normal position, Itwill be noted that the ball-actuating device may be moved immediately toposition to throw any of the transmission-gears into enga enient eventhough the ball and socket,

of this gear is not for the moment in register, and when this hap )ensthe ball-actuating device will bev turned against the tension of: thespring. so that when the ball-socket and balls opening come intoregister the ball-actuating device acting under the influence of thespring turnsand the slanting edges of the sleeve force the balls intoengagement.

The transmission-shaft has fixed on its end a gear G, which meshes withthe gear H This gear H has a sleeve-like hub 71, in which.

are ball-openings h. Balls 71 are arranged in these ball'openin s. Theshaft B is provided with the clutc -slots b, into which the balls areforced to lock the shaft B with the sleeve 71. A strap ii is mounted onthe sleeve. It has the cam-surface Z arranged to force the balls intothe clutch-slots b with an axial movement of the strap and the lips Zfor preventing the escape of the ballsfrom the opening. The strapL isprovided with the circumferential groove 1, in which are These pins aresecured These rock-arms are and this shaft is N in the plate arrangedthe pins 1. in the rock-arms L. mounted. on a shaft L mounted in theprojections N. A link M engages the pins Z and Z and thus connects thestraps I and L. A spring ll is tensioned against a projection Z and ashoulder Z on a pin L The end of the pin L is secured to one of the pinsZ, and the spring is tcnsioned so as to force the strap forward to setthe clutch through the action of the balls h. The link M where itengages the pin 11" has the slot m, which permits some play. When,therefore, the lever K is operated so as to force the strap I forwardand set the clutch with the ball it also moves the pin 11 in the slot 71and permits the spring L" to force the strap Ii forward. to set theclutch with the balls hf. If the link- M were positively connected tothe strap, or, in other words, if the strap were not provided with theslot m the balls h which are then in the stationary driven shaft B, maybe. in such position as to revent the immediate forward movement 0 thestrap. It becomes necessary, therefore, to )rovnle mechanism whereby theclutch witi the driving-shaft may be set and the setting of the clutchwith the driven shaft follows as soon as slot 6 is brought under one ofthe ball-o )enings h. f e variety It is desirable in order to add tot ofspeeds that may be attained to be able to connect the driving and drivenshafts directly. I have arranged a mechanism whereby this may beaccomplished through the action of the same controlling-lever K bymoving continuously that lever in the direction it has been moved tobring into action the higher speeds. The driving-shaft. A is providedwith the clutch-slots a. These are in the path of the ball-openings b inthe extension B. The balls openings 6 and are in the path of thecamsurfaces [J on the strap I. The lips 1) prevent the escape of theballs from the opening, but are of such size as to permit of the outwardmovement of the balls so as to disengage them from the driving-shaft.When the lever K has been moved forward so as to bring the in I at theend of the part 1) of the slot the ball-actuating device 1" has passedbeyond the balls f, or beyondthe highest-speed gear. A further movementof the lever moves the rock-arm. I, and with it the strap I and L, so asto release the clutches formed by the balls 0 and k2. A further movementof the lever through the. action of the part p of the cam-slot moves thearm I, so as to bring the strap 1 to a position to force the balls 1)into engagement of the clutch-slots a. This looks the shaft A directlywith the extension B, and consequently with the driven shaft. At thesame time t e transmission-gear has been thrown out both by the clutchformed with the openings h and the clutch formed with the openings c. Asthe lever is returned to the neutral point the clutch between thedriving are arranged in the 'and driven shaft is first released. Thenthe clutch formed by the balls h and c is thrown in, and the high-speedgear is picked up and the lower-speed gears in succession. The onlypurpose of providing the neutral point is to save the wearon the gears.Simply ringing the ball-actuating device 7'- to a position between thegears E and E would stop the driving action of the device; but themovement of the lever K not only brings the ball- .actuating device j tothat position, but also .brings the part p of the cam-slot into actionto throw on t the clutch between the drivingsleeve C and thedriving-shaft, so that the only wear is between the driving-sleeve anddriving-shaft. If it is desired to hax e a reverse movement of thedevice, the lever is .thrown still further in the backward direction,brin ing into action the part p of the cam-slot which throws the leverI", so as to throw in the clutch between the drive shaft anddriving-sleeve'C, and this movement of the lever also brings theball-actuating device 7' under the ball e, so as to lock thereverse-gear with the transmission-shaft.
